Create, edit, and wire up agenix-encrypted secrets in this dotfiles repo. Use when adding API keys, tokens, credentials, passwords, or any sensitive values to NixOS host configs. Trigger phrases: "add a secret", "encrypt with agenix", "new age secret", "hide this value", "agenix secret".

You are orchestrating a large, parallelizable change across this codebase.

Filter data at the source before it enters context. Use when querying APIs, CLIs, or databases where the full output would be large. Prefer structured output + jq/python filtering over dumping and scanning. Trigger phrases: "find the entity for", "get the ID of", "which service handles", "what's the value of", or any time you'd otherwise dump a large dataset to find one thing.

Split a monolithic Dagster job into per-asset schedules with individual healthchecks.io pings. Use when adding monitoring to Dagster assets, splitting a catch-all job, or wiring per-job healthchecks into the Nix bugster module.

Decomposes and reorganizes agent memory files into focused, single-purpose components. Use when memory has large multi-topic blocks, redundancy, or poor organization. Trigger phrases: "defrag memory", "reorganize memory", "clean up memory files", "split memory blocks".

Use when configuring Ghostty terminal emulator, working with ghostty config files, or looking up Ghostty settings and options.

Interact with Home Assistant via the REST API on a NixOS host. Use when adding integrations, querying entities, managing config flows, creating API tokens, or automating HA setup programmatically. Also covers identifying device protocols (Matter, Zigbee, Thread, HomeKit) from the device registry. Trigger phrases: "add HA integration", "configure home assistant", "query HA entities", "create HA token", "HA REST API", "pair homekit", "set up matter in HA", "add spotify to HA", "is this device zigbee or thread", "what protocol is this device", "move devices to ZHA", "identify matter devices".

Manage Home Assistant automations, scenes, and scripts declaratively via NixOS modules. Covers adding/editing/removing entities in the domain-based Nix structure, the ensureEnabled wrapper (initial_state enforcement), the sweep service that cleans orphaned entities, entity identity (IDs, slugs, unique_ids), the eval test assertions, and the build-time manifest. Trigger phrases: "add HA automation", "new scene", "new script", "remove automation", "declarative HA", "sweep unmanaged", "entity drift", "ghost entity", "orphaned automation", "HA domain file", "eval-automations test", "hass assertion", "ensureEnabled", "initial_state".

Create, manage, and verify healthchecks.io monitors via the REST API. Use when adding monitoring to a new cron job or service, auditing existing checks, wiring ping URLs into configs, or verifying a check fired correctly.

Entity-level code review with Ataraxy Labs inspect. Use when triaging PR/commit risk, ranking changed entities by impact, grouping tangled changes, or deciding review depth from blast radius/dependents.

Investigate jj commit history, split commits, annotate file changes, and clean up redundant commits. Use when debugging history, splitting large commits, or rewriting shared history.

Merges two separate Jujutsu (jj) repositories into one. Use when combining repos, rebasing one repo onto another, or recovering from diverged histories.

Ultra-performant HTML to Markdown Convertor Optimized for LLMs and llm.txt artifacts. ALWAYS use when writing code importing "mdream". Consult for debugging, best practices, or modifying mdream.

Write Nix modules with platform-specific options (NixOS vs Darwin) without infinite recursion. Use when mkIf causes evaluation errors or options don't exist across platforms.

Use when converting Pi config/extension/skill setup (Pi settings.json packages, ~/.pi/agent/extensions, git:... sources) into this dotfiles repo's Nix representation (skills-catalog/agent-skills-nix, modules/shell/pi/default.nix home.file links), or converting the other direction.

Use when writing standalone Python scripts (one-off scripts, utilities, not part of a larger Python project with pyproject.toml or setup.py). Provides UV shebang template and best practices.

Use this workflow for fast retrieval and lightweight maintenance.

Validates Claude Code skills against best practices for structure, content quality, and effectiveness. Use when creating new skills, reviewing existing skills, debugging skill invocation issues, or preparing skills for publication.

Debug and test tmux pane status detection for AI agents (opencode, claude, amp). Use when patterns aren't matching, status icons are wrong, or adding new detection patterns.

Set up isolated jj workspaces for parallel development. Use when creating new workspaces, organizing workspace directories, or setting up gitignore for workspaces.
